CNMG120412 T9215 indexable turning insert, CVD‑coated carbide, 80° rhombic — Tungaloy

The CNMG120412 T9215 is an ISO‑standard rhombic indexable turning insert designed for productive medium‑steel turning, offering a balanced mix of wear resistance and fracture toughness for continuous to lightly interrupted cuts.

• CVD‑coated carbide grade T9215
• Rhombic CNMG shape with 80° cutting geometry
• 1.2 mm corner radius for robust edge life
• Double‑sided chipbreaker and cylindrical hole

Productive medium‑steel turning through hardwearing grade selection

The CVD‑coated carbide grade T9215 combines high wear resistance with improved fracture resistance, making it especially suitable for medium‑steel workloads where stable tool life and consistent part quality are required. In practice, this means longer tool life, fewer insert changes and a more reliable machining rhythm; the chosen coating improves surface endurance under elevated cutting speeds while retaining edge stability during slightly interrupted cuts. The grade’s characteristics translate directly into measurable productivity gains on stable turning centres.

Consistent geometry and secure clamping for repeatable results

The rhombic CNMG geometry with an 80° cutting angle and a 1.2 mm corner radius provides a stable cutting edge that balances strength and finishing capability. The insert comes with a cylindrical hole and is produced to ISO tolerances, so compatibility with CNMG‑style holders depends on form, clearance angle, tolerance class, clamping method, size and thickness. Clearances such as the 0° relief minimise unwanted contact with the workpiece, supporting repeatable part dimensions and simplified re‑indexing during production.

Improved chip control and straightforward integration into existing tool systems

A double‑sided chipbreaker supports controlled chip formation across a range of feeds and depths of cut, reducing the risk of chip entanglement and assisting coolant flow at the tool tip. As an indexable insert, the component can be rotated or flipped to expose a fresh cutting edge, lowering tooling costs per component produced. Integration into existing ISO CNMG tool systems is uncomplicated: the insert forms part of a system that includes the appropriate external holder, shim and clamping screw, allowing a quick swap‑out and minimal machine downtime while improving surface finish and process stability.

FAQ

What materials is this insert optimised for?
The Tungaloy CNMG120412 T9215 grade is optimised for medium‑strength steels; the T9215 composition offers a balance of wear resistance and fracture toughness suited to continuous and slightly interrupted turning.

Is the insert indexable and reversible?
Yes, the CNMG120412 is an indexable, double‑sided insert that can be re‑indexed to present fresh cutting edges, helping to reduce tooling costs and maintain process continuity.

Which holders and systems are compatible with this insert?
Compatibility requires holders designed for ISO CNMG geometry; fit is governed by form, clearance angle, tolerance class, clamping method, size (12 mm) and thickness (4.76 mm), so CNMG‑type external holders with matching seat and clamp are recommended.

How does the T9215 grade improve productivity?
The CVD‑coated T9215 provides enhanced wear resistance and edge stability, which extends insert life and reduces interruptions for tool changes, leading to more consistent cycle times.

What chip control can be expected in practice?
The double‑sided chipbreaker promotes predictable chip formation across a range of feeds, contributing to improved surface finish and safer, more stable machining.
